No the point doesn't stand, you can't claim that something that isn't necessarily part of the role is defintitely part of the role. As for the rest my point is that I wouldn't care whether the players imperatively need those services, i would provide them anyway because my experience interacting with people and my personal experience is that you don't necessarily know what's good for you until someone more experienced tells you or something bad happens, if I was in a management role in football I would try to be proactive because I don't want to rely on 20 years old figuring life out faster than the rest of society.Yes, not all agents are the same. Some are commercial, some are contracts only, some are for business entity only, etc. It's now Roc Nation, his agency.
But the point still stands...someone, whether it was one person or one person with a full team, was representing Zaha and his rights during the transfer from Palace to United. That doesn't end after the transfer is completed, especially if your client has contractual obligations such as being a professional and acting/doing things in a way that will be positive and not detrimental to the club, players, or relevant employees.
So then again, it all points back to the player and club communicating what is needed. That same transfer window, United had other players who came in...don't hear them too much saying they didn't know how to cook thus not being able to feed themselves. So again, the club does enough and can do what is asked of them if they are asked by a player.
Here you Howard and Arenas mentioning it around 12:00.
